TKGm Nodes Configured with DHCP Fail to Boot

Products

• Tanzu Kubernetes Runtime

Issue/Introduction

TKGm nodes configured in DHCP fail to power on or become stuck during the boot process. 
The boot operation hangs at screen similar to the following:

Leases for reserved DHCP entries are not renewed when the node is powered on and may show as inactive. 
Leases for nodes that are unreserved do not appear in the DHCP server when the node powers on. 

Environment

TKGm

Cause

TKGm nodes configured to receive IP assignments from DHCP cannot boot if they are unable to reach DCHP server. 

Resolution

Please investigate the networking between the TKG environment and the DHCP server and the DHCP server configuration for any issues preventing communication.
